Driving less these days? If so, your car could be susceptible to battery failure.

To find out why, let’s go back to Chemistry 101: batteries produce electricity through an electro-chemical reaction – that is, electrons flowing from the lead oxide anode to the metallic lead cathode, through a solution of sulphuric acid.

That reaction happens much more slowly when the battery isn't in use, causing the battery to lose charge over time.

How long does that process take? It depends on a number of factors, such as the age of the battery, the weather, and the make/model of your car.

Certain cars drain particularly fast when parked, particularly the ones with all the computerized bells and whistles that continually suck power even when the car isn’t in use. Alarm systems, memory settings for radio and climate controls, etc., can all quickly drain a battery.

What’s the easiest way to prevent a dead batter? Simple: drive your car at least 10 kilometres, every three or four days. And if your car is going to sit parked for a while, consider disconnecting the battery's negative cable, or installing a smart charger that automatically shuts off once your battery is optimally charged.

Don’t feel too bad if your car won’t start one day. Remember that the average life span of a battery is only about three to five years, which is why it’s important to check on its health by giving CAA a call.
